Subject: core: abort hang DKG (#508)

* Capitalize log

* Fix DKG aborting hangs

Make sure reset cc.dkg to nil in runDKG

* Remember to purge tsig verfier too

* Replace abortCh with context.Context

* Fix obvious bug

* Fixup: forever blockin at Wait method when runDKG is not called

* Fixup: fix corner case

If the Add(1) moved to runDKG under cc.dkgLock,
we may not catch it after unlocking cc.dkgLock.

* fixup
